<h3>Import SRTM DEM</h3>

<p>Imports a tile of the&nbsp;<a href="http://www2.jpl.nasa.gov/srtm/">Shuttle Radar
    Topography Mission</a> (SRTM) elevation model&nbsp;at 3 arc
    second resolution.</p>

<p>The SRTM DEM Definition is intended to work with the SRTM 90m
    Version 4 in GeoTiff format.</p>

<p>If
    a requested tile is not found in the SRTM Folder specified in the
    Settings, then it will download the tile from the&nbsp;<a href="http://csi.cgiar.org/index.asp">Consultative Group
        for
        International Agriculture Research (CGIAR) - Consortium for Spatial
        Information</a> (CSI).</p>

<p>Since
    the SRTM height information&nbsp;is referred to geoid EGM96, not&nbsp;WGS84
    ellipsoid,&nbsp;correction has been applied to obtain height
    relative to the WGS84 ellipsoid.&nbsp;</p></body>
